            </div>
        </ContentTemplate>
    </asp:UpdatePanel>
</form>

I am loading modal from code behind and populate its fields from codebehind. Below is my codebehind code:

protected void up_tb8_Click(object sender, EventArgs e)
    {
        var db = new dbDataContext();
        Employee emp = new Employee();
        db.Sp_Updatevalue(up_id, up_tb1.Text, up_tb2.Text, up_tb3.Text, up_tb4.Text, Convert.ToDateTime(up_tb5.Text), up_tb6.Text, up_tb7.Text);
        ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "ClosePopup();", true);
     }

When I click my update button it successfully run my update stored procedure and update values from database. Question is when data update modal pop window was gone but its dim gray background still fixed on my screen I want to close modal properly when my records has been updated and my gridview refreshes and show my updated records.

Solution 1

If a user control (ascx) is wrapped inside the modal, then this:

 ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "$('#myModal').modal('hide');", true);

will NOT work. Instead of this, you should use this.Page .

Correct solution:

ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "Pop", "$('#myModal').modal('hide');", true);

Solution 2

You can try with this:

 ScriptManager.RegisterStartupScript(Page, Page.GetType(), "#myModal", "$('body').removeClass('modal-open');$('.modal-backdrop').remove();$('#myModal').hide();", true);

It works for me..!

Solution 3

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "#myModal1", "$('body').removeClass('modal-open');$('.modal-backdrop').remove();", true);

Solution 4

You can change your server button -

 <asp:Button ID="up_tb8" CssClass="btn btn-success" runat="server" Text="UPDATE" OnClick="up_tb8_Click" />

to something like this -

<button id="up_tb8" type="button" class="btn btn-default" data-dismiss="modal" runat="server" onserverclick="up_tb8_Click">UPDATE</button>

hope this will work
